TECHNICAL FIELD

The present invention relates to a system and a method for energy-savingair conditioning control via QR (Quick Response) code.

BACKGROUND

Smart air conditioning apparatuses were appeared on the market in about2010, and until now there are many different manufacturers join todevelop and manufacture the smart air conditioning apparatuses. Thesmart air conditioning apparatus may aim for several various purposes,such as energy-saving, enhancing the usability, increasing the comfortand user experiences, for example. It can be said that, the conventionalsmart air conditioning apparatus generally contributes for improving thequality of the air conditioning for users significantly.

However, by the observation of inventors, most of users use the smartair conditioning apparatus or a group of the smart air conditioningapparatuses have not yet fully exploited useful functions of them, whilemanufacturers may provide smart algorithms for integrating plurality ofcontrol modes according to various different purposes for the smart airconditioning apparatus, such as energy-saving mode, bedtime mode, etc.,many users may not understand correctly or not use correctly the controlmodes when referring to their living habits or their actual demands.Some of users, during their use, often unchanged or be slow to changeparameters or setting operation mode of the air conditioning apparatusin comparison with the time when they turn on, for example when turningon they may set the temperature very low and keep unchanged untilfeeling uncomfortable, for example feeling very cold before they performa change, for example increasing the temperature and decreasing the fanspeed.

In addition, the setting of the temperature is very low and the fanspeed is very high when turning on the air conditioning apparatus mayalso happen at many public areas, may be at areas where the adjustmentof the operation of the air conditioning apparatus not specificallyassigned for anyone, even the operation situation may last while thereis no one presented at the area where the air conditioning is employed,for example.

The smart air conditioning apparatuses are also said that they notchange the operation mode according to the changes of the factors ofsurrounding environment or habits of the users.

Because the energy needed to use for the air conditioning, generally forall society is very huge, the energy-saving, or in particularly, theelectricity-saving during the using of the air conditioning apparatuseshave a very important meaning. Although the smart air conditioningapparatuses may solve a part of the problem of the energy-saving in anindividual operation mode of them, the energy-saving in general termssuch as an adequately adjustment corresponding to the surroundingenvironment, habits of users, when there are many air conditioningapparatuses commonly operate in a same space or in a same system, issupposedly that not solved very well.

As for that, there is a need of an air conditioning monitoring andcontrol approach may solve the energy-saving problem or theenergy-saving solution which is more overall and optimally.

Furthermore, the old generation air conditioning apparatuses arecurrently in use with a quite huge number. Due to the lifetime of theair conditioning apparatuses are relatively long, and when it is in acomparison with the development of the intelligent control technologiesthe lifetime of the air conditioning apparatuses may be said to be verylong time. Therefore, as for the air conditioning apparatuses, even the“old generation” smart air conditioning apparatuses, upgrading them isvery difficult.

Hence, there is also a need of an air conditioning monitoring andcontrol approach may solve the energy-saving or electricity-savingproblem, may be applicable supplemental equipped for existed airconditioning apparatuses, to be for using new control algorithms, forexample intelligent control algorithms aimed to the energy-saving.

As for conditioning apparatuses are used at places that provides apublic service for many people, such as at universities/schools,hospitals, restaurants/shops, or similar areas. Starting and running theconditioning apparatuses using handhold remote controls are usuallyseparate, may lead to a repetition needed for a control operation forplurality of conditioning apparatuses so that it is possible to be usedfor an entire desired area. If the conditioning apparatuses are not fromthe same manufacturer, or from the same brand but there are differentmodels, may lead to an inconvenience, for example due to a wrong choiceof a handhold remote control or a confusion between different airconditioner brands. In addition, may easily be forgotten or lost, anddifficulty in monitoring and assigning for who are authorized tocontrol.

As for some lines of air conditioning apparatuses may be controlled viasoftware applications, for example applications installed onsmartphones.

Genuine air conditioning control applications have appeared, however,most of these applications are only developed with control sharingfeatures for home use only, therefore it is substantially difficult orimpossible in sharing control rights for employees to use to implementat places that provide a public service for many people.

Air conditioner control applications are developed by third partiesoften integrating many different models for users to select, theselection may be via different names or icons. However, for relativelylarge number, will cause problems for those who are not very familiarwith technology, for example spending extra time or choose the wrongmodel.

Hence, there is also a need of a conditioning control approachimplemented at places that provides a public service for many people,which is convenient to use and control for both users andadministrator/manager.

Therefore, it should be understood thatembodiments described herein is only exemplary for fully understandingof the inventive steps and advantages of the present invention, withoutany limitation of the present invention to the embodiments.

Herein, the air conditioning apparatus is basically a device with afunction to maintain the room air at a stable settingtemperature/expected temperature to provide an environment which is morecomfortable for users, the temperature stabilization may be cooling downthe air or heating the air. Several two-way air conditioning apparatusesgenerally include both air cooling function and air heating function,whereas several air conditioning apparatuses have only one function forcooling the air may be called as an air cooling device/air conditioner,or only one function for heating the air may be called as a heater.

Common features of the two-way air conditioning apparatus orconventional air conditioner may include two components which are acondenser unit and an evaporator unit, these two components may bearranged integrally in one package, may be called as a packaged airconditioner or a window air conditioner (mainly used in US market, oldgeneration). If these two components are arranged at two different areasthey may be divided into two categories which are wall an airconditioner/ceiling air conditioner, and so called “mother-hold-baby”air conditioner with one condenser unit and plurality of the evaporatorunits.

In most of the designs the air conditioning apparatus always includes anindoor unit, and may be equipped a control board fixed on the wall, or ahandheld remote control (infrared remote control). When using thehandheld remote control, the indoor unit of the air conditioningapparatus generally includes a signal receiving face for receiving theair conditioning control signal from the handheld remote control. It isobviously that, the air conditioning apparatus may be controlled by thesimilar conditioner control means which is operated by users, forexample a smartphone device installed a dedicated app, for example.

When the user performs the operation to turn on the air conditioningapparatus, an air conditioning control signal (or a control command)will be transmitted to the air conditioning apparatus to be operatedcorresponding to setting parameters and/or operating mode according tothe control command of the user. Counting from that time, the airconditioning apparatus will generally operate according to the settingsof the control command (the initial control command) correctly, untilthe user proactively changes, for example transmitting a new controlcommand This has been analyzed that it is difficult to achieve theenergy-saving purpose if the user does not have a correct habits orconsciousness.

In general, conditioning control signals are sent/transmitted to aconditioning apparatus or a group of conditioning apparatus via wired orwireless means according to a typically manner which is sent wirelesslyfrom handhold remote controls, or wiredly from wall-mounted controlpanels. However, these control signals may be sent via intermediumcomponents or any means which simulates control signals of said wiredmeans or wireless means, for example smartphone, devices that receivingand retransmitting control signals, but not limited thereto. Inaddition, said devices that receiving and retransmitting control signalsmay also receive the control signals via many means and in manydifferent manners.

FIG. 1 illustrates a method for energy-saving air conditioning controlvia QR code according to an embodiment of the present invention.

As shown in FIG. 1 , the method for energy-saving air conditioningcontrol via QR code according to the embodiment comprising the stepsfrom S101 to S104 as described in more details hereafter.

The step S101: generating a QR code in the vicinity of a location of anair conditioning apparatus or a group of air conditioning apparatusescorresponding to a predetermined space to be cooled. The QR code may beprinted or coated on any material, for example paper, plastic,composite, at a convenient position that facilitates the user to reachand scan the QR code. However, the present invention is not limitedthereto, the QR code may be also display in an electronic image form aslong as it is of a fixed nature in the vicinity of the location of thecorresponding air conditioning apparatus or the corresponding group ofthe air conditioning apparatuses and convenient for the user to reachand scan the QR code.

The QR code contains an air conditioning apparatus identifier associatedwith the air conditioning apparatus or the group of air conditioningapparatuses. The air conditioning apparatus identifier may help todefine a list including one or more than one air conditioning apparatuscorresponding to a predetermined space to be cooled, therefore it isable to precisely control air conditioning apparatus(es) in a space byscanning the QR code which is provided at this space. In addition, it isalso favorable for creating preset modes, control modes which areinstalled according to specific targets (for example, energy-saving), orcustomized by the owner's needs, ensuring a reasonable use and avoidingarbitrary settings or controls, for example setting the temperature toolow, causing waste of electricity.

The present invention may use any system or manner for generating saidQR code, and assigning a corresponding air conditioning apparatus or acorresponding group of air conditioning apparatuses associated with theQR code.

Herein, the group of air conditioning apparatuses may be understood in abroad sense, wherein the group of air conditioning apparatuses mayinclude one or more than one air conditioning apparatuses, and otherdevices as well, such as lighting devices, fans, projectors, multimediaplayers, electrical equipment or electronic equipment, etc., but notonly limited thereto.

The step S102: scanning the QR code by a handheld electronic device. TheQR code stands for “Quick Response code”, or also be called“Matrix-barcode” or “two-dimensional (2D) barcode”. In other words, theQR code is a form of information that is encoded for display so that itcan be read and decoded, and may contain information such as URL,security code, password, description or an introduction of a certainproduct, time and location of the event, or any information, for exampleinformation which is represented by alphanumeric characters.

One QR code allow relatively large amounts of transmitted information tobe contained in the QR code, good support for providing the necessaryinformation thereto.

According to the present invention, the scanning of the QR code havingthe purpose to retrieve the information contained in the scanned QR codefor usage in various embodiments of the present invention.

According to an embodiment, a retrieved information in the QR code maycontain at least an URL link, an identifier of the air conditioningapparatus or the group of air conditioning apparatuses corresponding toa space needs to be cooled with QR code scanned. Such that, just byscanning operation on the QR code, the user is able to access an URLlink, the URL link may be, such as a web application for example, toaccess applications which are built on a web platform, for example anair conditioning control interface on the web, but not only limitedthereto.

According to another embodiment, the retrieved information in the QRcode may contain at least a login password, an identifier of the airconditioning apparatus or the group of air conditioning apparatusescorresponding to a space needs to be cooled with QR code scanned. Sothat, just by scanning operation on the QR code, the user is able toaccess applications which are built on a mobile device platform (forexample, in apps store Android, iOS, or similar), such as an airconditioning control interface on a smartphone or a handheld electronicdevice, but not only limited thereto.

The step S103: determining the user identifier.

It is obviously that, to access the air conditioning control interface,or perform control operations therein, the user needs to be determinedby the user identifier. If the user identifier is invalid then the userwill not be able to access the air conditioning control interface, ornot be able to perform control operations therein.

The determination of the user identifier may be performed throughvarious appropriate manners.

For example, the determination of the user identifier may be performedby entering a student code, an employee code, a usage assigned code, orsimilar codes or characters. These codes may be entered for the firsttime and will be saved in the electronic device associated with theassigned user, after that when scanning the QR code by the handheldelectronic device the determination of the user identifier will beautomatically determined using these saved code mentioned above.

According to an example, depending on the choice of the manager or theowner of the conditioning apparatus or the group of conditioningapparatus, the determination of the user identifier may be performed byentering the usage assigned code.

The usage assigned code may be sent to the user from the manager or theowner for a convenience for the management of assigning usage rights tousers. The code may be disabled by the manager or the owner after thatto prevent the user continue to use the corresponding conditioningapparatus or the corresponding group of conditioning apparatus.

The usage assigned code may be printed, displayed, or expressed in avisible form at a predetermined space to be cooled where there is thecorresponding air conditioning apparatus or the corresponding group ofair conditioning apparatuses. By this manner, the user only needs topresent there for scanning the QR code and entering the usage assignedcode to access the air conditioning control interface for controllingthe air conditioning apparatus or the group of air conditioningapparatuses there.

It should be understood that the present invention is not limited to anymanners used for scanning the QR code and determining the useridentifier. Appropriate manners are provided according to differentpurposes of the manager or the owner when designing the system, andtherefore, they are within the scope of the present invention.

The step S104: accessing the air conditioning control interface forcontrolling the air conditioning apparatus or the group of airconditioning apparatuses, if the user identifier is valid. Preferably,the air conditioning control interface including one or more than onepredetermined air conditioning control mode corresponding to the airconditioning apparatus or the group of air conditioning apparatusesassociated with said scanned QR code.

In general, the present invention is not just intended to a convenientand effective usage for starting and running the air conditioningapparatus(es) by scanning the QR code and determining the validation offthe user identifier, but also intended to other purposes as well, forexample energy-saving, by associating the air conditioning apparatus orthe group of air conditioning apparatuses with the scanned QR code, itis therefore able to define or preset air specific conditioning controlmodes for the air conditioning apparatus or the group of airconditioning apparatuses to achieve the expected targets, for exampleenergy-saving.

It is obviously that, the present invention may provide many variousdifferent air conditioning control modes, and may select a part of thoseto provide groups of control modes including one or more than one airconditioning control mode suitable for each practical application. Whenthe air conditioning apparatus or the group of air conditioningapparatuses are associated with a QR code, it may be installed accordingto a group of control modes as well, thus when the user accesses the airconditioning control interface by scanning the QR code and the useridentifier is valid, the air conditioning control interface onlydisplays expected air conditioning control modes in the group of thecontrol modes which are preset for the corresponding air conditioningapparatus or the corresponding group of air conditioning apparatuses. Bythis manner, the usage of the air conditioning apparatuses issubstantially controlled according to expected targets/purposes, forexample responding exactly to the actual needs of users, and optimizingsubsequent operations, for example soft adjustments within theappropriate temperature range, adjustments following to changes of thesurrounding environment, etc., to achieve expected targets, for exampleenergy-saving.

In addition, in several specific applications, the present invention mayallow the user to optionally adjust according to user settings at thestarting time and running the air conditioning apparatus, this may beperformed by setting up an optional air conditioning control mode tofacilitate the users who expect to control according to their personalpreferences. When the users adjust themselves according to theirpersonal preferences, warnings (for example increasing in theelectricity consumption or wasting in the electric energy) may beanalyzed and sent to the users.

In the actual usage of an air conditioning apparatus, there may be manydifferent manners provided or designed to satisfy needs of the userswell. For example, when using air conditioning apparatus(es) in meetingroom, classroom, or similar places, usually of a pre-planned nature, forexample the meeting start time, the class start time, or similar startevents times, then the turn on plan of the air conditioning apparatus orthe group of air conditioning apparatuses before the start time of theseevents, for example before that time from 5 to 10 minutes or 10 to 20minutes or a certain predetermined time duration, may provide asignificant comfort for users and participants joined said events.

According to above mentioned embodiments, the turning on of the airconditioning apparatus or the group of air conditioning apparatuses onlyperformed by scanning the QR code and validating the user identifier,that means there are only few certain users be able to turn on. To turnon before the start time of said events, those users must be present atthe appropriate time, may cause some inconveniences. Therefore, thepresent invention provides the approach that automatically turns on theair conditioning apparatus or the group of air conditioning apparatusesbefore the start time of the event in a predetermined time duration (forexample, from 5 to 20 minutes). and to ensure that the subsequent use isvalid, then it is necessary to have a valid user, who is a user amongthe certain users be able to turn on mentioned above, to be presentthere and perform scanning the QR code and to ensure that thedetermination of the user identifier is valid. If there is not any validuser be present there then the air conditioning apparatus or the groupof air conditioning apparatuses will automatically turn off after apredetermined period of time. This not only ensures the usage of the airconditioning apparatus or the group of air conditioning apparatuses isthen controlled and responsible by a valid user, but also avoiding aninvalid usage, or for some reasons, the event does not take placeaccording to the schedule/plan, the air conditioning apparatus or thegroup of air conditioning apparatuses after turning on automatically,will turning off automatically after a predetermined period of time, notbe forgotten and running in a long period of time while there is noevent takes place or there is no one be present there, for example.

Thus, the control of the air conditioning apparatus or the group of airconditioning apparatuses via the air conditioning control interfacefurther comprising a control for maintaining a previously installedoperation of the air conditioning apparatus or the group of airconditioning apparatuses, wherein the previously installed operation ofthe air conditioning apparatus or the group of air conditioningapparatuses is to start and run according to a predetermined scheduleduring a predetermined time duration. If after this predetermined periodof time, a controlling operation for maintaining a previously installedoperation is not carried out, then the air conditioning apparatus or thegroup of air conditioning apparatuses will turn off automatically.

Herein, controlling for maintaining the operation may be understood thatkeep maintaining the air conditioning apparatus or the group of airconditioning apparatuses in running operation, or it may be understoodin another way as not being turned off. It is obviously that, the validusers may change control modes according to their expectations afterscanning the QR code and determining the valid user identifier.

According to an embodiment, the air conditioning control interface maybe displayed on an application installed in a handheld electronic devicewhich the user uses for scanning the QR code, for example a smartphone.The handheld electronic device may be configured to simulate airconditioning control signals and directly send control commands to theair conditioning apparatus and the group of air conditioning apparatusesto start and run the air conditioning apparatus. Appropriate controlmodes may be downloaded to the handheld electronic device based on theuser identifier assigned corresponding to the specific air conditioningapparatus(es) or the group(s) of the specific air conditioningapparatuses.

According to various embodiments of the present invention, the airconditioning control interface may be connected to the air conditioningapparatus or the group of air conditioning apparatuses by at least oneof options including: (i) an intermedium air conditioning controldevice, (ii) a server, and an intermedium air conditioning controldevice, and (iii) a server, a gateway, and an intermedium airconditioning control device.
